- Nb of programs created: hard without revenue Explorer. You can just use the naming convention to filter the programs you want, select all the list in Marketo, paste it to and excel spreadsheet and count
- total email sent: email performance report will give you this.
- active trigger campaigns: go to the campaign inspector, you will see them and the count will be displayed at the bottom right corner of the screen
- email assets created: another tricky ones. Use your naming convention to filter, filter on emails, then do the copy paste in Excel.
Thank you, Grégoire! I have moved the question to "products".
